We investigated glutathione level, activities of selenium independent GSH peroxidase, selenium dependent GSH peroxidase, GSH S-transferase, GSH reductase and the rate of lipid peroxidation expressed as the level of malondialdehyde in liver tissues obtained from patients diagnosed with cirrhosis or hepatocellular carcinoma. GSH level was found to be lower in(More)
The aim of the study was an evaluation of changes in protein level and activity of SOD isoenzymes, and the participation of AP-1 and NF-kappaB in subsequent stages of colorectal cancer development. Studies were conducted on 65 colorectal cancers. Controls were unchanged colon regions. Activity of SOD isoenzymes, lipid peroxidation level (TBARS), and protein(More)
Sodium diethyldithiocarbamate (DETC) is the main metabolite of disulfiram. Recently, we reported that mechanism of disulfiram cytotoxicity in V79 cells might be partially connected with thiol redox-state imbalance. Here, we examined the effect of DETC on the level of intracellular glutathione (GSH), protein oxidation (measured as PC—protein carbonyl(More)
The aim of this study was to evaluate changes in the enzymatic antioxidant system in rat small intestine caused by invasion of tapeworms Hymenolepis diminuta. The study material consisted of samples of the rats small intestine after short- (1.5-months) and long-term (1.5-years) larvae invasion of tapeworm H. diminuta. In tissue extracts the concentration of(More)
The aim of the present paper was to describe the enzymatic antioxidant system in Hymenolepis diminuta collected from rats exposed to chronic cestode invasion. We dissected different tissues of H. diminuta (immature proglottids, genital primordia, hermaphroditic proglottids, early uterus, and gravid uterus) and studied activity of: superoxide dismutases(More)
